Any particulate filter eventually clogs, so you have to replace it as breathing becomes difficult..任何微粒过滤器最终会阻塞，所以当感到呼吸困难时，你必须更换它。

We tell you not only are they teeming with life, but the planets and stars and the space particulate between are themselves all conscious beings..我们告诉你，不只那些（有形体）上满布着生命体，而且行星、星体和空间微粒之间也满布着有意识的存有。

...the particulate pollution in our atmosphere.....我们大气中的颗粒污染。
